gimmer, be sure to check the clearance of the chain in relation to the bottom of the oil tank. Ive heard of another member "larkfarms" trying to mount a mini keg underneath and the chain needed to be accounted for. You might have to cut out a notch for the chain. I think it wasnt a problem until weight was put on the suspension in normal driving situations. Of course it depends on how big the tank is. Just a thought, before you have anything painted..haha
